问题描述

我有一个现有的动态Web项目.现在，我正计划参加这个项目. 我可以知道如何实现吗?

I am having a exsting dynamic web project. Now I am planning to maven to this project. May I know how can I acheive that?

推荐答案

首先，一旦创建了Web项目类型，更改它就不好了，这是不好的做法.您应该在开始项目之前决定将其作为动态Web项目还是使用Maven进行.当您执行此操作时，这将帮助您避免在将项目类型转换为其他类型时避免很多错误，并且当您使用IDE创建例如Maven项目时，它将根据您的项目配置自动构建基础.

First of all it's not good to change web project type once you have created one it's bad practice. You should either decide before you begin your project to do it as dynamic web project or with maven. When you do this it would help you to avoid lots of errors when converting project type to another and also when you use IDE to create for example Maven project it would build the base automatically based on your project configurations.

但是可以将动态Web项目转换为Maven.这是您需要做的:

However it is possible to convert dynamic web project to Maven. Here's what you need to do:

如果您使用的是Eclipse，则只需在项目上右键单击鼠标，然后从菜单配置->转换为Maven项目中进行选择即可.如果这不起作用，那么您必须用困难的方式做到这一点，即:

If you are using Eclipse, you can simply do this by right-clicking your mouse on your project and choose from menu Configure -> Convert to Maven Project. If this doesn't work then you have to do it with hard way, which is:

1. 创建Maven项目文件夹结构

1. Create Maven project folder structure

• 您需要将所有现有的Java源文件移至\src\main\java
• 将web.xml移至\src\main\webapp\WEB-INF
• 创建pom.xml文件并将其放在项目根文件夹中. (如果由于某种原因您没有上述文件夹，则需要相应地创建它们)

• You need to move all exiting java source files to \src\main\java
• Move web.xml to \src\main\webapp\WEB-INF
• Create pom.xml file and put it in your project root folder. (If for some reason you don't have above folders then you need to create them accordingly)

在pom.xml文件中配置项目详细信息. 这是 pom.xml文件，其中包含项目详细信息.

Configure project details in pom.xml file. Here's an example of pom.xml file that has project details.

配置依赖项库.这意味着您需要将在Web项目中使用的所有库添加为pom.xml中的依赖项.

Configure dependency libraries. This means that you need to add all libraries you use in your web project as dependencies in pom.xml.

使用mvn compile命令编译您的项目.要运行此命令，您需要转到项目文件夹，然后在此处运行它.如果使用Windows，则必须在命令提示符下执行此操作；如果使用Linux，请使用终端.

Compile your project with mvn compile command. To run this command you need to go to your project folder and then run it there. If you are using Windows then you must do this in command prompt, if you are using Linux, use Terminal.

(可选)，如果要使项目支持Eclipse IDE，请运行以下命令mvn eclipse:eclipse -Dwtpversion=2.0.

(Optional) If you want to make your project support Eclipse IDE then run following command mvn eclipse:eclipse -Dwtpversion=2.0.

现在，您需要生成.war文件以进行部署.为此，您必须使用命令提示符/终端再次进入项目文件夹，并运行以下maven命令mvn war:war.这将在您的项目目标文件夹中生成WAR文件.

Now you need to generate .war file for purpose of deployment. To do this you must go again to your project folder using command prompt/Terminal and run following maven command mvn war:war. This will generate WAR file in your project target folder.
